Description

Technical Field

[0001] The utility model relates to the technical field of electroplating wastewater treatment, in particular to an electroplating wastewater treatment and reclaimed water reuse device. Background Technique

[0002] Electroplating wastewater contains a large amount of metal ions, such as copper, chromium, nickel, zinc, etc. These metal ions are highly toxic to water bodies and the ecological environment. Therefore, electroplating wastewater needs to be treated. After treatment, not only can the pollution of electroplating wastewater to water bodies and the ecological environment be reduced, but also reclaimed water that can be recycled can be obtained. The treatment process mainly includes two steps: precipitation and filtration. That is, by adding appropriate precipitation agents such as calcium hydroxide or sodium hydroxide, the suspended solids and some heavy metal ions in the electroplating wastewater are precipitated, so as to remove the suspended solids in the wastewater. Then, the electroplating wastewater is filtered to remove the solid particles after precipitation, so that the electroplating wastewater is purified to obtain recyclable reclaimed water. During the precipitation process, the precipitated impurities are easily attached to the inner wall of the container.

[0003] Patent CN220788212U discloses an electroplating wastewater treatment tank, which can not only make the stirring mechanism stir the wastewater at different positions to improve the reaction treatment effect, but also automatically clean the inner wall of the treatment tank. However, after the electroplating wastewater is purified, the impurities on the inner wall of the treatment tank are only scraped off, and the scraped impurities are still in the treatment tank, which requires staff to clean the impurities, not only increasing the labor intensity of the staff, but also affecting the treatment efficiency of electroplating wastewater.

[0022] The following will describe in detail an electroplating wastewater treatment and reclaimed water reuse device proposed by the present utility model with reference to the drawings.

[0023] As Figure 1 、 Figure 2As shown in the figure, the electroplating wastewater treatment and reclaimed water reuse equipment includes a housing assembly and a cleaning assembly. The housing assembly includes: a housing 1 of a closed cylindrical mechanism placed horizontally, a first motor 2 fixedly connected to one end of the housing 1 and capable of driving the housing 1 to rotate around its own axis, a support mechanism 3 provided below the housing 1 to support the rotation of the housing 1, an impurity discharge port that can be opened and closed is provided at one end of the housing 1, a water inlet pipe 4 connected to the connection water inlet valve 41 and a water outlet pipe 5 connected to the connection water outlet valve 51 are connected to the outer wall of the housing 1. When injecting water into the housing through the water inlet pipe 4 and discharging the water in the housing 1 through the water outlet pipe 5, the impurity discharge port is in a closed state; the cleaning assembly 6 includes a scraper 61 accommodated in the inner cavity of the housing 1 and the edge of which can be slidably pressed against the inner cavity wall of the housing 1 in close contact. The scraper 61 can move back and forth in the inner cavity of the housing 1 through a transmission structure. When the scraper 61 moves back and forth in the inner cavity of the housing 1, the impurity discharge port is in an open state.

[0024] In practical applications, electroplating wastewater and an appropriate amount of precipitation agent are injected into the inner cavity of the housing 1 from the water inlet pipe 4. Immediately afterwards, the first motor 2 drives the housing 1 to rotate, so that the electroplating wastewater and the precipitation agent in the housing 1 are quickly mixed and react, precipitating the suspended solids and heavy metal ions in the electroplating wastewater, completing the treatment of the electroplating wastewater, obtaining preliminarily recyclable reclaimed water. Then, the water outlet valve 51 is opened, and the reclaimed water from which heavy metal ions and suspended solids have been separated is discharged from the housing 1 through the water outlet pipe 5. After that, the scraper 61 is moved in the inner cavity of the housing 1 through a transmission structure to scrape the precipitated impurities on the inner cavity wall of the housing 1, and at the same time, the impurity discharge port is opened to discharge the scraped precipitated impurities from the housing 1, eliminating the process of manually removing the precipitated impurities on the inner cavity wall of the housing 1, reducing the labor intensity of the staff, and also improving the treatment efficiency of the electroplating wastewater.

[0025] Such as Figure 2As shown, the shell 1 includes a cylindrical structure 11 with one end closed and a sealing cover 12 that is rotatably sealed and connected to the opening of the cylindrical structure 11. The first motor 2 is connected to the closed end of the cylindrical structure 11. The outer side of the sealing cover 12 is fixedly connected to the first limit plate 7. The lower end of the first limit plate 7 is fixedly connected to the support mechanism 3. A first discharge port 111 is provided on the wall of the cylindrical structure 11. A second discharge port 121 located directly below the cylindrical structure 11 is provided on the wall of the sealing cover 12 where the sealing cover 12 is connected to the cylindrical structure 11. When the cylindrical structure 11 rotates until the first discharge port 111 is located at the bottom end of the cylindrical structure 11, the first discharge port 111 and the second discharge port 121 are connected. The discharge port 121 is aligned, and the sealing ring 13 that can cover and seal the second discharge port 121 is rotatably connected on the sealing cover 12. A gear ring 14 is nested and fixedly connected on the outer wall of the sealing ring 13. A driving gear 8 that meshes with the gear ring 14 is provided below the gear ring 14. The driving gear 8 is connected to the second motor 9. A third discharge port 131 is provided on the wall of the sealing ring 13. When the sealing ring 13 rotates to the point where the third discharge port 131 is located at the bottom end of the cylindrical structure 11, the third discharge port 131 is aligned with the second discharge port 121. When the first discharge port 111, the second discharge port 121 and the third discharge port 131 are all aligned, the impurity discharge port is in an open state.

[0026] In actual application, the sealing cover 12 is fixedly connected to the first limiting plate 7, and the second discharge port 121 on the sealing cover 12 is always directly below the cylinder structure 11. During the rotation of the cylinder structure 11 driven by the first motor 2, the third discharge port 131 on the sealing ring 13 should be staggered with the second discharge port 121 to avoid the first discharge port 111, the second discharge port 121, and the third discharge port 131 from being aligned. That is, to ensure that the impurity discharge port is in a closed state, in this embodiment, before the cylinder structure 11 rotates, the third discharge port 131 is first rotated to the cylinder structure 11 through the driving gear 8. Directly above the structure 11, that is, it is staggered with the second discharge port 121 directly below the cylindrical structure 11. After the electroplating wastewater and the precipitation agent are fully mixed to obtain reclaimed water and the reclaimed water is discharged from the shell 1, the sealing ring 13 is driven by the driving gear 8 to rotate to the position where the third discharge port 131 is directly below the cylindrical structure 11. At this time, the first discharge port 111, the second discharge port 121, and the third discharge port 131 are all aligned, and the impurity discharge port is in an open state. At the same time, the scraper 61 moves in the inner cavity of the shell 1 through the transmission structure, scrapes off the impurity precipitation on the inner cavity wall of the shell 1, and discharges the impurity precipitation through the impurity discharge port.

[0027] like Figure 2 、 Figure 4As shown in the figure, the transmission structure is specifically as follows: a positioning plate 62 rotatably connected to the inner wall of the closed end of the cylindrical structure 11, a first through hole 612 with internal threads provided on the inner wall is formed on the scraping plate 61, a screw rod 63 whose thread is in threaded engagement with the first through hole 612 is movably connected in the first through hole 612, one end of the screw rod 63 is rotatably connected to the positioning plate 62, and the other end extends out of the sealing cover 12 and is connected to the third motor 64. The third motor 64 has a forward and reverse function. An openable and closable diversion port 611 penetrating the scraping plate 61 is provided on the scraping plate 61. A limiting block 65 is fixedly connected to the screw rod 63 near the inner wall of the closed end of the cylindrical structure 11. The water inlet pipe 4 and the water outlet pipe 5 are respectively located on the horizontal and upper and lower sides of the limiting block 65. A second through hole 613 is also formed on the scraping plate 61, and a guide rod 66 passes through the second through hole 613. Both ends of the guide rod 66 are fixedly connected to the positioning plate 62 and the sealing cover 12 respectively.

[0028] In practical applications, since the positioning plate 62 connecting the screw rod 63 and the guide rod 66 is rotatably connected to the inner wall of the closed end of the cylindrical structure 11, during the rotation of the cylindrical structure 11, the screw rod 63 and the guide rod 66 will not be driven to rotate by the cylindrical structure 11 but remain stationary. Therefore, the scraping plate 61 will also remain stationary, ensuring that during the mixing process of electroplating wastewater and precipitation agents, the precipitation impurities on the inner cavity wall of the cylindrical structure 11 will not be scraped into the mixed solution of electroplating wastewater and precipitation agents due to the movement of the scraping plate 61 in the cylindrical structure 11, which affects the precipitation effect and the quality of reclaimed water.

[0029] When the cylindrical structure 11 rotates, the scraping plate 61 is located at the position of the limiting block 65, and the diversion port 611 of the scraping plate 61 is in a closed state. Since the water inlet pipe 4 and the water outlet pipe 5 are respectively located on the horizontal two sides of the limiting block 65, at this time, the scraping plate 61 can isolate the electroplating wastewater and the precipitation agents in the inner cavity of the housing 1 on one side of the water inlet pipe 4. After the electroplating wastewater and the precipitation agents are fully mixed, the cylindrical structure 11 stops rotating. According to the liquid level of the reclaimed water in the housing 1, the diversion port 611 is opened to an appropriate position, and the reclaimed water will be discharged from the housing 1 through the diversion port 611 and the water outlet pipe 5, while the impurity precipitation remains in the housing 1. Subsequently, the third motor 64 can be used to drive the screw rod 63 to rotate, thereby driving the scraping plate 61 to move in the inner cavity of the cylindrical structure 11 to scrape off the precipitation impurities on the inner cavity wall of the cylindrical structure 11.

[0030] As Figure 2 、 Figure 4 、 Figure 5 As shown in the figure, a sealing plate 67 that can slide up and down relative to the diversion port 611 is provided above the diversion port 611. The sealing plate 67 is connected to the scraping plate 61 through a sliding mechanism 68. The sliding mechanism 68 includes two waterproof covers 681 symmetrically installed on the scraping plate 61 with respect to the sealing plate 67 and electric telescopic rods 682 installed in the waterproof covers 681. The output ends of the electric telescopic rods 682 are fixedly connected to the sealing plate 67.

[0031] That is, the position of the sealing plate 67 on the diversion port 611 is controlled by the telescopic movement of the electric telescopic rod 682, so that the diversion port 611 is opened at the corresponding height according to different intermediate water levels and impurity precipitation heights.

[0032] As Figure 2 As shown in the figure, above the support mechanism 3 is a supporting groove 31 with a circular arc-shaped cross-section adapted to the outer wall of the housing 1. A number of first rotating grooves 32 are provided in the supporting groove 31. First balls 33 are rotatably connected in the first rotating grooves 32. A number of first sliding grooves 15 surrounding the housing 1 and adapted to the first balls 33 are provided on the outer wall of the housing 1. This rotational design similar to a bearing mechanism can ensure the smooth and stable rotation of the housing 1.

[0033] As Figure 2 、 Figure 3 As shown in the figure, a number of second rotating grooves 122 are provided on the circumferential outer wall of the sealing cover 12. Second balls 123 are rotatably connected in the second rotating grooves 122 of the sealing cover 12. Second sliding grooves 132 for the second balls 123 to rotate are provided on the inner wall of the sealing ring 13. The above structural design ensures that the sealing ring 13 can rotate smoothly on the circumferential outer wall of the sealing cover 12, and at the same time can ensure that the sealing ring 13 will not slip off the sealing cover 12.

[0034] As Figure 2 As shown in the figure, a protruding rotating shaft 621 is provided at the center of the positioning plate 62. A bearing 622 is sleeved on the rotating shaft 621. A groove 112 adapted to the outer wall of the bearing 622 is provided on the inner wall of the closed end of the cylindrical structure 11 to ensure the smoothness of the relative rotation between the positioning plate 62 and the cylindrical structure 11.

[0035] As Figure 2 As shown in the figure, a second limiting plate 10 for restricting the horizontal movement of the housing 1 is provided at the closed end of the cylindrical structure 11. The rotating shaft of the first motor 2 passes through the second limiting plate 10 and is fixedly connected to the closed end of the cylindrical structure 11. The second limiting plate 10 can keep the housing 1 in a better horizontal position and will not shake during the working process, ensuring the stability and safety of the device.

[0036] An observation window made of a transparent material such as glass can also be provided on the housing 1 to observe the liquid level and other conditions inside the housing 1, so as to better judge what corresponding operation measures should be taken.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
